BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a refrigerating apparatus such as refrigerator, a freezer, a wine cabinet, or a combination thereof and a method of controlling cooling climate of the apparatus and displaying control elements. The refrigerating apparatus has an interactive, ergonomic cooling control system.

2. Description of Related Art

Prior art refrigerating appliances typically include one or more refrigerating or freezer compartments for the storage of fresh and frozen foods. Typically, the temperature settings for the fresh food compartment and the freezer compartment were adjusted by manipulating an electromechanical mechanism such as a dial or a sliding switch. Usually these systems provided no apparent way to determine the actual temperature of the compartments and the temperature settings were often determined by user trial and error.

More recently, electronic controls have offered various control schemes the user including, for example, digitally displaying the temperature of a compartment. However, electronic controls can be confusing and, to a large extent, the setting of temperature of a particular compartment remains a trial and error operation. Also, while some refrigerating appliance have climate zones with fixed humidity for certain types of food, there is lack of appliances that permit the adjustment of the humidity. It should be readily apparent that adding adjustment of humidity to adjustment of temperature across multiple compartments increases the complexity and likelihood for potential user confusion in controlling a refrigerating appliance. Therefore, there is a need for a climate control system in refrigerating appliances that provides the user with an interface that is easy to use and easy to understand while at the same time capable of handling complex temperature and humidity adjustments for multiple compartments.

Referring now to FIGS. 5 through 10B, interface display 30 has a climate control activation element 42. The display elements may be any suitable icon or icons, graphical depictions, pictograms, text, or the like. The selection of icons may vary with language and culture of the region where the refrigerating appliance is intended to be used. In this preferred embodiment, the climate control activation element is a graphical depiction of a thermometer.

In a preferred embodiment, interface display 30 comprises compartment selection element 41. In this embodiment, compartment selection element 41 comprises four pictogram icons 44, 45, 46, 47 representing compartments 28, 24, 26, 22, respectively. In alternative embodiments, the refrigerating device may have two or more compartments with compartment icons of compartment selection element 41 corresponding to each compartment of the device. Preferably, interface display 30 additionally has two climate control elements 43, 48. Climate control element 43 is a temperature control icon having a numeric temperature display sub-icon 52 and temperature adjustment sub-icons 51, 53. Activation of the temperature adjustment sub-icons causes the device to adjust the temperature of the selected compartment. Climate control element 48 is a presentation of a plurality of food-type icons 61, 62, 63, 64, 65, and 66. In this embodiment, each icon is textual: FRUIT, MEAT, DELI, DAIRY, FISH, and VEG, representing the specific food types of fruit, meat, deli products, dairy products, fish, and vegetables, respectively. In varying embodiments, climate control element 48 may comprise any variety of preset food type icons. Activation of a selected food-type icon causes the system to adjust the climate of the selected compartment to predetermined climate conditions associated with the selected food type. In a preferred embodiment, at least one compartment permits activation of more than one food-type icon, and the device is capable of adjusting the climate of the selected compartment to predetermined climate conditions associated with the combination of selected food types. In preferred embodiments, the predetermined climate conditions are temperature, humidity, or both temperature and humidity. Interface display 30 may also have icons for functionalities other than climate control of specific compartments. For example, icon 55 (SUPER) activates a supercooling function when selected in conjunction with climate control change. Icons 56, 57, and 58 (ICE, ALARM, and FILTER, respectively) may actuate an ice-making function, an alarm function, and a filter function, respectively.

In the operation of a preferred embodiment, the elements of the interface display are presented sequentially as user selections are made. FIG. 6A illustrates the display of only the activation element 42. When the user selects activation by touching activation element 42, compartment selection element 41 is displayed as shown in FIG. 6B. Also, preferably, activation element 42 changes color to indicate that its has already been selected. FIG. 7A illustrates the display icon 44 of compartment selection element 41 is selected. In this case, temperature control icon 43 is displayed and the compartment icon 44 is changed in color to indicate selection. Also in this case, the food-type icons 48 are not displayed, because compartment 28 corresponding to icon 44 is not designed to permit a variance of humidity. Upon actuation of sub-icon 51, the temperature setting is reduced to the temperature displayed in the temperature display sub-icon 52 as shown for example in FIG. 7B. FIG. 7C illustrates the selection of the supercooling function in conjunction with the temperature change selection. The SUPER icon 55 preferably changes color upon actuation.

Any suitable colors may be used to indicate selection choices. For example, prior to selection (or if an icon is not selected), the icon may be displayed in white and, upon selection, the icon may be displayed in yellow. While the preferred embodiment illustrates the combination of sequential display and color changes to indicate the selection sequence and selection choices, respectively, it will be readily appreciated that other highlighting methodologies may also employed such as a first color change for selection sequence and a second color change for selection choices. Other graphical indicators may also be used for selection sequence and selection choices.

With reference to FIGS. 8A and 8B, the plurality of food-type icons is displayed when either of icons 45 or 46, corresponding to compartments 24 and 26, are actuated. In this embodiment, these compartments are designed to effect temperature and humidity changes depending on the type of food to stored in the compartment. FIG. 8A illustrates that compartment 24 was selected and icon 45 has changed color. Similarly, FIG. 8B illustrates that compartment 26 has been selected and icon 46 has changed color.

FIGS. 9A, 9B, and 9C illustrate a preferred embodiment of interface display 30 when food-type icons 62 (MEAT), 65 (FISH), and 66 (VEG) have been sequentially selected for compartment 26. In the case where multiple food types have been selected, the control device will alter the temperature and humidity to predetermined levels to take into consideration the optimal temperature and humidity levels for the selected combination. Thus, there is no need for the user to experiment through trial and error to determine the optimum temperature and humidity values for one food type or any combination of food types. The interface provides an intuitive and user-friendly means to make complex climate control decisions for individual compartments of the refrigerating appliance.

FIGS. 10A and 10B illustrate a preferred embodiment of interface display 30 when icon 47, corresponding to freezer compartment 22, is activated. In this case, temperature control icon 43 is displayed and compartment icon 47 is preferably changed in color to indicate selection. Also in this case, the food-type icons 48 are not displayed, because freezer compartment 22 corresponding to icon 47 is not designed to permit a variance of humidity. In FIG. 10B, SUPER icon 55 is activated and, in a preferred embodiment, changes color.

FIG. 11 shows an exemplary interface display 70 for a three-compartment wine cabinet, FIG. 12 shows an exemplary interface display 72 for a freezer, and FIG. 13 shows an exemplary interface display 74 for a three-compartment refrigerator. One of skill in the art will appreciate that the number of compartments may be varied depending on the type of refrigerating apparatus. Accordingly, interface display 30 may be modified such that compartment selection element 41, temperature control icon 43, and food-type icons 48 appropriately correspond to the climate control compartments of the particular refrigerating apparatus.
